(0]..91-30) This invention relates a. the coating of textile fabrics with rubber, cellulose derivative or other compositions in a spreading machine, and has for its object to provide improved means for coating fabrics in a uniform manner right up to andincluding the edges so that fabrics without selvedges,

or tubular (circular) fabrics, can be given any desired coating without leaving uncoated strips and without necessitating, in the case of plain or rligln-tubular fabrics, any trimming of the edges. e invention is also concerned with the production of multiply fabrics in which the plies are connected by an adhesive.

In accordance with my invention, side controls are spaced from, the edges of the fabric softhat a (Figure 2) to bring one or other gauge edge into service. v

The compound, which is of suitable consistency, viscosity or composition, for spreading purposes.

(and may be a rubber or a synthetic rubber subthe compound in advance of the spreading gauge not only covers the whole width of the fabric but can trickle or overflow at its edges. 7

The invention further comprises the provision of selvedge scraper blades to remove any excess of coating compound which may tend to creep round the edges of the fabric after it leaves the spreading The invention further comprises the uniting of two lengths of fabric between doubling or combining rollers after one or both fabrics has or have been coated with adhesive by a spreading gauge arranged as before described.

Referring to the accompanying explanatory drawings:

Figure l is a side elevation, Fig. 1a is a detail view similar to Fig. l with parts removed to more clearly show the spreadinggauge and associated elements, Figure 2 a plan view and Figure 3 a front view looking from left to right in Figure 1, showing a fabric coating machine constructed in one convenient form in accordance with this invention.

In Figures 1-3, the fabric a to be'coated is fed over a roller b, the height of which is adjustable and under a spreading gauge 0, and it may then pass over a second roller (1 which can be adjusted in height. The fabric isheld up to the gauge edge by its own tension- Side-plates m together with side controls e secured thereto are dovetailed into the spreading gauge as indicated at 0 and are axially adjustable therealong to suit the width of fabric being treated. The side controlse pro- .iect forward from the spreading gauge and lie at opposite sides of the fabric at a Shvl't distance therefrom so that as the compound spreads out due to the movement of the'fabric, some will overflow or trickle over the edges of the fabric and be diverted bychutes' (not shown) into suitable receptacles beneath.

stitute or a cellulose derivative) is fed on to the I spreading gauge c down a plate h set at an angle so as to form a trough with the gauge. The plate It is pivotallymounted at n in the side plates m,

to the fabric may be varied by altering the angle of approach of the fabric to the spreading gauge and/or its angle of delivery therefrom. This can be effected by adjusting the heights of the rollers b and d or of the spreading gauge 0. Also the consistency or viscosity or composition of the compound or mixture may be altered for the same purpose. g

In the case of \tubular fabrics. these may be folded flat, and coated at both sides so that the whole of the outside of the tube is evenly coated.

. obviates dimculties dueto loose'threads or other imperfections at the fabric edges, as these with my improvement become bound in 'by the compound which trickles over and'so effectually coats the edges.

lily-invention is particularly advantageous for use in coating balloon and dinghy fabrics, bias fabrics and fabrics without'selvedges, and delicate materials. I f

The process can be applied to fabric which has been previously coated in a calender or by spreading or impregnating with rubber or like substance.

What I claim is: 1. A fabric coating machine comprising a spreading gauge having two gauge edges, an arrgularly adjustable-plate forming a trough with, and leaving a gap between itself and the gauge, the coating compound being fed into such trough, a roller over which the fabric passes in advance of the gauge, and a similar roller over which the fabric passes at the rear of the gauge, the fabric being depressed by the gauge in its passage between the two rollers, the extent of such depression being regulated by adjusting the relative heights of the rollers and gauge, side controls to limit the extent to which compound can flow over the edges of the cloth from the spreading gauge,

and means for turning the gauge to bring the desired edge into service. I

2. A fabric coating machine comprising a spreading gauge, means for adjusting said gauge, side controls attached to and adjustable with said auge, an angularly adjustable plate carried by said controls and forming a trough with and leaving a gap between itself and the gauge, rollers arranged in advance and at the rear of said gauge over which the fabric passes, the fabric being depressed by the gauge in its passage between the two rollers and the extent of such depression being regulated by adjusting the relative heights of the roller and gauge, said side controls limiting,

the extent to which the compound can flow over the edges of the cloth from the spreading gauge.

3. A fabric coating machine comprising a spreading gauge, means for holding the fabric up to said gauge only by its tension, side controls spaced from the edges of the fabric whereby the compound in advance of said gauge not only covers the whole width of the fabric but also overflows by gravity at such edges, and selvedge scraper blades for removing any excess of coating compound which maytend to creep round the edges of the fabric after it leaves said gauge.

4. A fabric coating machine comprising a spreading gauge, means for holding fabric up to said gauge only by its tension, side controls carried by said gauge and spaced from the edges of the fabric whereby the compound in advance of thegauge not only covers the whole width of the fabric but also overflows by gravity at said edges, and selvage edge scraper blades, also carried by said gauge positioned beyond the side controls for gauge, the bottom of the gauge being positioned to deflect downwards-a fabric passing between said rollers and beneath the gauge, adjustable side controls spaced from the edges of the fabricand spreading gauge to limit the extent to which coating compound can flow over the edges of the fabric from between the spreading gauge and cloth salvage scraper blades positioned beyond the side controls to scrape the fabric seivages and remove any excess coating compound which may tend to creep around the edges of the fabric.
